There are very few humans now who live a totally hunter/gatherer life style, and modern tech and modern products are pushing into those lives, changing them.
We keep changing things, call it progress, call it the sin of mankind, call it what you want, it is a part of being human.
So, if we go back far enough, trains were a new idea that was never going to work or happen. And trains did work, did happen, tracks got laid, freight and humans moved farther, faster because of that change, those trains put a lot of stage lines and horse/mule/oxen drawn freight wagons out of business, along with impacting the jobs and income of those raising that livestock, tending that livestock from freight stop to freight stop and all those building and maintaining those wagons, and those drivers. Everyone adapted, like it or not, adapting is what humans do and can do well.
That horseless buggy was never going to be more than a toy for the rich, cars, trucks and buses are everywhere now, and even farm equipment, and that again changed how we did things, put people out of work, into new jobs, changed our lives, we cannot and would not change them back.
And again technology, humans thinking and creating had changed our lives and the world. The Internet, and portable Internet using devices, has changed the world.
And we will see renewable energy changing the world, impacting those in the fossil fuel industries, we will see fewer and fewer coal mines, a slow down in crude oil development, a slow down and shut down of coal fired power plants. It is happening now, and will continue to happen. It will and already has impacted towns and people in coal mining areas, around the world, and is is shutting down coal fired power plants, and impacting those jobs and those towns.
It will keep happening, people need to look to the future and accept that they might be able to slow down those changes but they cannot stop them. Fighting to keep those changes from happening might slow them down, but it does not help anyone look to the coming future and plan for it, find ways to work with it, find other strengths that can bring other jobs to their areas, find ways to look at dealing with the coming changes instead of fighting them.
I am not really fond of change, but I know fighting it only makes it harder for me long term, so as our plant changes ownership, I too, have to adjust to changes and plan to deal with how they impact my life, my income, my future. I expected to retire from my current employer, but they are selling, not only our plant, but their entire pork division, so many will be dealing with this change,vat least 5100+ employee in our plant alone. So, I am not alone in this coming change, and most of us will cope, adapt, adjust and keep our lives working and moving on, in this changing world we humans keep changing.
